I thought I'd see lots of PV generation from Hugh Aston this weekend (17th-18th May), but it seems not. Any ideas why we didn't see big chunks taken out of consumption this weekend, despite the weather looking like this?
The generation is obvious over the weekend of the 3/4/5th, but not this weekend (see pic below)

I agree, this looks a bit wrong, especially on the 17th of May.
I would expect the PV to generate loads over this last weekend. Comparing to the 10th of May where I can see a dip in the middle of the day cancelling out the peak of consumption. The 17th looks like a simple consumption peak with no PV influence. Compare also to back in early March.
It may be that the PV generation is maxed out for a long period. This would produce a flattened, wide generation peak.Possibly a very wide peak would sit on top of the consumption peak and only make it a bit flatter and lower rather than invert it?
Even without considering the PV the weekend use on 17th/18th seems on the high side. If PV is taking a chunk out of consumption the building was unusually active. Perhaps @DMU_Energy or @carlholland have some supporting data/information?

Normal service resumed this Sunday gone, although Saturday still looked strange for a weekend. Graphs here.
The more I learn from this data, the less I think I know. Why does the electricity go up so much on Monday and Tuesday? The uni was shut... There must be loads of timed systems (lights? Aircon?) that just come on regardless of occupancy, I guess.
